Alfonsine Tables
The ''Alfonsine Tables'' (, ), sometimes spelled ''Alphonsine Tables'', provided data for computing the position of the Sun, Moon and planets relative to the fixed stars. The tables were named after Alfonso X of Castile, who sponsored their creation. They were compiled in Toledo, Spain, and contain astronomical data starting on June 1, 1252, the date of the coronation of the King. Production Alfonso X assembled a team of scholars, known as the Toledo School of Translators, who among other translating tasks, were asked to produce new tables that updated the '' Tables of Toledo''. The new tables were based on earlier astronomical works and observations by Islamic astronomers, adding observations by astronomers Alfonso had gathered in Toledo, among them several Jewish scholars, like Yehuda ben Moshe and Isaac ibn Sid. He also brought Aben Raghel y Alquibicio and Aben Musio y Mohamat, from Seville, Joseph Aben Alí and Jacobo Abenvena, from Córdoba, and fifty more from Gas ...

Georg Purbach
Georg von Peuerbach (also Purbach, Peurbach; ; 30 May 1423 – 8 April 1461) was an Austrian astronomer, poet, mathematician and instrument maker, best known for his streamlined presentation of Ptolemaic astronomy in the ''Theoricae Novae Planetarum.'' Peuerbach was instrumental in making astronomy, mathematics and literature simple and accessible for Europeans during the Renaissance and beyond. Biography Peuerbach's life remains relatively unknown until he enrolled at the University of Vienna in 1446. He was born in the Austrian town of Peuerbach in upper Austria. A horoscope published eighty-nine years after his death places his date of birth specifically on 30 May 1423, though other evidence only indicates that he was born sometime after 1421. He received his Bachelor of Arts in 1448. Georg's intellect was discovered by a priest of his hometown, Dr. Heinrich Barucher. Dr. Barucher recognized Peuerbach's academic abilities from a young age and put him in contact with the Augus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solar System

The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document.

It Formation and evolution of the Solar System, formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.

Geocentric Model
In astronomy, the geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system) is a superseded scientific theories, superseded description of the Universe with Earth at the center. Under most geocentric models, the Sun, Moon, stars, and classical planet, planets all orbit Earth. The geocentric model was the predominant description of the cosmos in many European Ancient history, ancient civilizations, such as those of Aristotle in Classical Greece and Ptolemy in Roman Egypt, as well as during the Islamic Golden Age. Two observations supported the idea that Earth was the center of the Universe. First, from anywhere on Earth, the Sun appears to revolve around Earth diurnal motion, once per day. While the Moon and the planets have their own motions, they also appear to revolve around Earth about once per day. The stars appeared to be fixed stars, fixed on a celestial sphere rotating once each day about celestial pole, an axis through the geogr ...

Ptolemy
Claudius Ptolemy (; , ; ; – 160s/170s AD) was a Greco-Roman mathematician, astronomer, astrologer, geographer, and music theorist who wrote about a dozen scientific treatises, three of which were important to later Byzantine science, Byzantine, Islamic science, Islamic, and Science in the Renaissance, Western European science. The first was his astronomical treatise now known as the ''Almagest'', originally entitled ' (, ', ). The second is the ''Geography (Ptolemy), Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian physics, Aristotelian natural philosophy of his day. This is sometimes known as the ' (, 'On the Effects') but more commonly known as the ' (from the Koine Greek meaning 'four books'; ).

John Of Lignères
John of Lignéres or Johannes de Lineriis () was a French astronomer who wrote several works on the calculation of moon, sun, and planetary positions. Many of his works are confounded with the works of similar named Parisian astronomer collaborators and students including Johns of Murs, John of Sicily, John of Saxony, and John of Montfort. His works were important in importing Arabic astronomical calculations into European traditions. John was from Amiens and lived in Paris from 1320 to 1335. He may have been born in Ligneres, 37 km southeast of Amiens. Little is known of his life other than his writings. He is considered as the key promoter of the Alfonsine tables The ''Alfonsine Tables'' (, ), sometimes spelled ''Alphonsine Tables'', provided data for computing the position of the Sun, Moon and planets relative to the fixed stars.

John Of Saxony (astronomer)
John of Saxony (also Johannes de Saxonia, John Danko or Dancowe of Saxony) was a medieval astronomer. Although his exact birthplace is unknown it is believed he was born in Germany, most likely Magdeburg. His scholarly work is believed to date from the end of the 13th century into the mid 14th century. He spent most of his active career, from about 1327 to 1355, at the University of Paris. Scholarship John of Saxony is quoted in various medieval manuscripts and referenced as the author of various astronomical or astrological treatises, even though his authorship in some cases is questionable. A ''computus'' dating back to 1297 is attributed to John of Saxony even though the author is listed as Iohannes Alemanus. The fact that the geographical longitudes of Paris and Magdeburg, considered John's birthplace, among other facts is why some historians consider him the author. Viewed with less suspicion is his commentary on ''Liber Introductorius ad Magisterium Idiciorum Astrorum'' w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horoscopes
A horoscope (or other commonly used names for the horoscope in English include natal chart, astrological chart, astro-chart, celestial map, sky-map, star-chart, cosmogram, vitasphere, radical chart, radix, chart wheel or simply chart) is an astrological chart or diagram representing the positions of the Sun, Moon, planets, astrological aspects and angles at the time of an event, such as the moment of a person's birth. The word horoscope is derived from the Greek words ''ōra'' and ''scopos'' meaning "time" and "observer" (''horoskopos'', pl. ''horoskopoi'', or "marker(s) of the hour"). It is claimed by proponents of astrology that a horoscope can be used as a method of divination regarding events relating to the point in time it represents, and it forms the basis of the horoscopic traditions of astrology, although practices surrounding astrology have been recognized as pseudoscientific since the 18th century. Horoscope columns are often featured in print and online newspapers. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
